In the above diagram, I have a phone line that comes into a DSL modem. the packets then go from the first router to the second router and to the server. I can ping connections to the outside world from the server.

What I am trying to figure out is it possible to set up port forwarding from the first router to the second router and make it connect to the server. The routers that I have are Linksys.

Router 1
192.168.2.1
255.255.255.0

Router 2
192.168.1.1
255.255.255.0

Server
192.168.1.x (where x is from 10 to 15)
255.255.255.0

I do understand the basics of routing. as where the default gateway for the server is 192.168.1.1 in which the default gateway for that router is 192.168.2.1 which then proceeds to the internet.

Any help would be greatly appreciated as I would like to keep the networks separated like they are. If not, I might have to get my older Cisco 10mbps routers out and try to figure that out.
